NEEDLE PLATE WORKTABLE Filed June 3. 1929 ATTORNEY WITNESS:

Patented Oct. 13, 1931 UNITED STATES ISIDORE KRASNE, OF TULSA, OKLAHOMA NEEDLE PLATE WORKTABLE Application filed June 3, 1929. Serial No. 368,054.

This invention relates to a needle plate work table for needle machines used in the manufacture and repair of shoes, the general object of the invention being to provide means whereby a great number of parts of the machine as now constructed is eliminated, so that the cost of manufacture of the machine is greatly reduced, as well as the cost of operation and the invention facilitates the cleaning of the machine and prevents the soiling of the shoes. The invention also renders other parts of the machine accessible so that they can be adjusted without loss of time or danger of getting some other parts out of order, and provides more room so that the shoe can be stitched with more ease.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, il-

lustrated in the accompanying drawings and specifically pointed out in the appended claim.

In describing the invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure l is a fragmentary view, sh wing 0 the invention applied to a needle machine of the curved needle type.

Figure 2 is a front view showing the va rious parts of the invention.

Figure 3 is a top plan view.

In these views, the numeral 1 indicates a supporting member or table which is adapted to be attached to a part of the machine by the bolts 2,-this member having a substantially horizontally arranged curved front part 3 which extends between the needle l and the looper 5, the said part having an opening 6 therein through which the needle passes, it being understood that the sole of the shoe is placed on said front part in such a position that the needle will pass through the sole and welt during the sewing operation. A curvedplate 7 has its upper end fastened to the front edge of the part 3 and'extends downwardly and inwardly, as shown. This plate covers the front part of the opening 6 and acts as a shield for the upper of the shoe, it being understood that the shoe is turned upside down during the sewing operation, so that the plate protects the upper from damage by the awl and needle and also prevents the upper from being soiled. An upright perforated stud 8 is formed on the free end of the member 1 and a threaded hole communicates with the perforation in said stud and adapted to receive a set screw 9. 2i guiding member 10, of slightly curved formation, is held above the part 8 of member 1 having a projection 11 at one end thereof entering the perforation in the lug 8, said projection being held in adjusted position in the lug by the set screw 9. This member acts a stop for the edge of the sole and by adjusting the member, the sole can be so positioned in the machine that the a-wl and needle will pass through the desired part thereof or through the previously formed stitching holes. This member also enables the machine to sew on from the narrowest to the widest welt.

It is thought from the foregoing description that the advantages and novel features of he invention will be readily apparent.

it is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claim.

hat I claim is z- In combination with a welt stitching ma.- chine, a bracket having one end attached to the machine, with a subsantially horizontal part at its other end which is provided with an opening through which the needle or awl passes, a slightly curved guiding bar ar ranged over the horizontal part and forming a stop for the edge of the sole being sewn, said guiding bar having a right angular projection adjacent one end thereof, a perforated upstanding projection on the horizontal part through the perforation of which the projection passes and a set screw for holding the projection in adjusted position in said perforated part. 7

In testimony whereof I affix my signature.

ISIDORE KRASNE.
